Distribution of Some Risk Factors Related to Soft Tissue Injuries in Dentoalveolar Traumas/Dento Alveolar Travmalarda Gorulen Yumusak Doku Yaralanmalariyla Baglantili Risk Faktorlerinin Dagilimi.

Introduction

The oral region accounts for as little as 1% of the total body size. However, injuries to this region account for 5-33% of all injuries among all ages (1,2). Traumatic dental injuries often result in soft tissue injuries. Osunde et al. (3) observed soft tissue injuries in 70% of all patients with maxillofacial traumas. Diaz et al. (4) reported that 39% of dento-alveolar traumas were accompanied by soft tissue injuries. In spite of this fact, the soft tissue injuries might be exposed to ignorance by the dentists who primarily focus on the patients' traumatized teeth.

Soft tissue traumas are usually seen as abrasion (rubbing or scraping of the mucosa), contusion (a bruise caused by a blunt object), laceration (tear in mucosa), and rarely seen as penetration (produced by sharp object) and avulsion (loss of tissue) (2).

Inadequate emergency care of soft tissue injuries in dento-alveolar traumas may cause economic, psychological, and aesthetic problems (5). There is limited research on the relationship between soft tissue injuries and dento-alveolar traumas (3,6). Although soft tissue injuries in children decrease with age, Osunde et al. (3), found out that this was not the case in dento-alveolar injuries (3).

The null hypothesis was that the soft tissue injuries in children, who referred to a pedodontics clinic with dento-alveolar traumas have no difference according to gender, age, localization (lips, gingiva, cheeks, tongue, and perioral tissues), wound type (abrasion, laceration, contusion, and mixed), time elapsed before treatment, and the relationship of these factors to the trauma classification.

Material and Methods

The study protocol was approved by the Ethics Committee of the Ataturk University Faculty of Medicine (reference number: 2013/40). A retrospective study was conducted in eastern Anatolia region, Turkey. The study included 268 records of patients (166 boys and 102 girls) aged 1-15 [8.19[+ or -]3.90 standard deviation (SD)] with dento-alveolar traumas who were examined and treated for different injuries in the university dental clinic between April 2010 and July 2015. Of these 268 patients, only 90 had soft tissue injuries.

The inclusion criteria for this study were patients with dento-alveolar traumas who had presented to the clinic within seven days of the injury and who had not sought any dental treatment earlier. The exclusion criteria were dento-alveolar fractures with severe skeletal deformities in the head and neck region, and patients who had injured themselves after receiving local anesthesia.

The dento-alveolar trauma records included the patient's gender, age, affected dentition and localization (lips, gums, cheeks, palate, floor of the mouth, and tongue), classification of soft tissue injury (abrasion, laceration, contusion, and mixed), and the time interval between trauma and treatment. The dento-alveolar trauma was classified as injuries to the hard dental tissues and pulp, root fracture, injuries to the supporting tissues, and multiple injuries (7).

Statistical Analysis

Data analyses were carried out using SPSS software (SPSS for Windows, version 20.0, SPSS Inc., Chicago, IL, USA). Comparisons were performed with [chi square] tests and the Mann-Whitney U test, where appropriate, to investigate the association between various factors related to the dental trauma and the characteristics of the trauma. The comparisons were followed by logistic regression analyses of the dento-alveolar traumas impact on soft tissue injury types. The statistical significance level was set at p<0.05.

Results

In total, 268 children with dento-alveolar traumas presented to our clinic within one week of the injury [males, n=166 (61.9%); females, n=102 (38.1%)]. The percentage of soft tissue injuries in traumatic dental injuries experience was 31.9% in males and 36.3% in females. Therefore, females were found to be more prone to experience soft tissues injury in case of dento-alveolar trauma. Despite the numerical and proportional differences in the soft tissue traumas, there was no difference according to gender ([chi square]=0.53, p=0.46).

There was no statistically significant difference (p=0.32) in the mean age of the patients with soft tissue traumas (7.87[+ or -]3.69 SD) and the mean age of the remaining 178 children (8.35[+ or -]4.0 SD).

The null hypothesis was rejected. Soft tissue injuries were increased in the mixed dentition period (6-12 years) (n=47), reaching the highest between the ages of 8 and 10 (Figure 1). The primary dentition period (0-6 years) was the next most common time of the injuries (n=32). The incidence of soft tissue traumas decreased after the age of 12 ([chi square]=17, p=0.36). The ratio of soft tissue injuries in the dento-alveolar traumas ranged between 21% and 83% according to age (Figure 2). The ratio was generally between 2142% whereas, it was more than 50% for the ages of 4-6 years.

The localization of the soft tissue injury types is shown in Figure 3. The frequencies of soft tissue injuries in children were 43.3% for lacerations, 30% for the mixed (more than one type of soft tissue injuries), 18.9% for contusions, and 7.8% for abrasions. Only, four patients with lacerations had penetration injuries. There was a statistically significant difference between the frequencies of abrasions and those of the other soft tissue injury types ([chi square]=20.79, p=0.008). Most of the soft tissue injuries were in the maxilla (n=78, 86.7%), followed by the mandible (n=5, 5.6%) and both jaws (n=7, 7.8%). Also, the distribution of soft tissue injuries in the maxilla and mandible fits that of the injuries to the teeth ([chi square]=3.84, p=0.045).

Figure 4 depicts the treatment times of the patients. Twenty-two (24.4%) children with soft tissue injuries received treatment on the same day, 47 (52.2%) in 2-3 days, and 21 (23.3%) within 4-7 days. There was no statistically significant difference in the arrival times of the children with and without soft tissue injuries (p=0.401).

Figure 5 shows the association between the dento-alveolar trauma and the resultant wounds. Among the 90 patients with soft tissue injuries, 58 (64.4%) had injuries to the supporting tissues, 20 (22.2%) had hard dental tissue and pulp injuries, 9 (10%) had multiple injuries, and 3 (3.3%) had hard dental tissue injuries. There was a statistically significant difference in the soft tissue injuries, resulting from supporting tissue injuries (p=0.001 [chi square]=15.72). Soft tissue injuries in the primary dentition were the consequence of supporting tissue injuries (84.8%). And in the permanent dentition soft tissue injuries originated from supporting tissue injuries (52.6%) and hard dental tissues and the pulp injuries (31.6%).

Discussion

Traumatic dental injuries are usually accompanied by soft tissue injuries. In this study the soft tissue injuries in children were evaluated according to various factors. The null hypothesis was rejected. In our study, the frequency of soft tissue injuries was 33.6%, which is similar to the distribution of dental injuries reported to be 30-50% in other studies (1,4,8,9). Similar to our findings, many studies showed that males are more prone than females to dento-alveolar trauma (10,11). However, we found no statistically significant difference in soft tissue injuries according to gender in common with other studies (12-15).

Although there was no statistically significant difference in age, the patients with soft tissue injuries were younger (7.87[+ or -]3.69 SD) than those without soft tissue injuries (8.35[+ or -]4.0 SD). Severe trauma as a result of poorly developed defense mechanisms, muscle coordination, and motor skills may affect the frequency of soft tissue injuries in younger children (14-17). In our study, soft tissue injuries and dentoalveolar injuries were common in mixed dentition, with the highest frequency found in children aged 8-10 years. As reported in the literature, children aged 1-4 years are most susceptible (among all ages) to accidents and have the highest number of soft tissue injuries (3,6,12,14,16,18). Studies have also reported that younger children who have a higher cranial vs. facial skeletal size, softer and more elastic bones, and protective thick soft tissues are more likely to be exposed to minor injuries, such as soft tissue injuries, whereas older children tend to be more susceptible to serious injuries (6,17,19). Vuletic et al. (20), found that soft tissue injuries peaked among preschool children aged two years (18). After the preschool period, the superego develops, and the child is exposed to disciplined training at school (19,21). As reported in the literature, such training can decrease injury rates among those aged 4-6 years, even among children from disorganized families (19,21). Nevertheless, in the present study, the highest percentage of soft tissue injuries in dento-alveolar traumas was observed among the children aged 4-6 years and particularly among those aged five years.

In dento-alveolar trauma, soft tissue injuries are seen most frequently in the maxilla, especially in the upper lip (20,22). As reported in the literature, the high incidence of such injuries may be due to the protrusive structure of the maxilla (4,11,13,21,23). In the present study, soft tissue injuries were most frequently found in the maxilla as previous studies.

Fractures of the molar teeth may be associated with traumatic injuries to the chin (22,24). In our study only one patient had extrusive luxation and laceration on his permanent maxillary left first premolar caused by facial collision into a doorknob following slippage.

In studies of soft tissue injuries in maxillofacial and dento-alveolar trauma patients, lacerations accounted for 37.5-83.4%, contusions accounted for 8.4-32.8%, and abrasions accounted for 1.629.7% (4,6,13,15,23,25). Similarly, the frequency of lacerations in our study of soft tissue injuries was 43.3%, whereas the frequency of mixed injuries, contusions, and abrasions was 30%, 18.9%, and 7.8%, respectively.

Abrasions are observed more commonly in perioral than intraoral tissues and are therefore less common than other types of injuries. A traumatic force with a high intensity, which could lead to dento-alveolar injury, may cause lacerations as the most frequent type of soft tissue injury (24,26). Many lacerations resulting in swellings may be due to a combination of crushing and tearing of tissue. As noted in the literature, special attention should be paid to children with such injuries because healing occurs faster than in adults, resulting in the rapid formation of hypertrophic scars and keloids (25,27).

In Eastern Anatolia Region, most emergency management of children's tooth injury trauma is undertaken by pediatric dentistry department. The most important principle in the treatment of soft tissue injuries is debridement of the wound and thorough cleaning with saline (20,22). Lacerations were treated with suture. Antibiotics were prescribed, depending on the severity of the injury. If the patient has not received tetanus prophylaxis in the previous five years, patients were referred to hospital for additional doses (25,27).

After the occurrence of soft tissue injury, new tissue formation lasts between 4-30 days (10,26). Meanwhile, relatively simple soft tissue injuries, including contusion, heals within one week (11,27). For this reason, the dento-alveolar trauma patients who were admitted within one week, were included in this study. Also, there was a statistically significant difference in the arrival time of the children with and without soft tissue injuries. Vuletic et al. (20) reported that children with soft tissue injuries presented earlier for dental treatment (18). However, there was no difference in the presentation time of those with soft tissue injuries in our study. With regard to the presentation time for dental treatment, the majority of the children with soft tissue injuries presented on the second day after the injury, followed by the first and third post-injury days. Among the patients who sought treatment within the first 24 hour, the frequency of those who presented within 2 hour of the injury may be explained by the sensitivity of parents to soft tissue injuries. Delays in the initial treatment might be due to a large number of the referred patients living some distance from the clinic, the absence of an after-hours dentist, unawareness of the after-hours service, giving a low priority to dental injuries, and not considering emergency management of dental injuries a priority.

According to a previous study, the most common type of dento-alveolar trauma was hard dental tissue and pulp injuries in permanent dentition and

supporting or hard dental tissue and pulp injuries in primary dentition (28). A literature search revealed no relationship between soft tissue injuries and dento-alveolar trauma. In our study, we observed soft tissue injuries more frequently in injuries to the supporting tissues (64.4%) than injuries to the hard dental tissues and pulp (22.2%). With regard to tooth injury mechanisms, one study found that a low-velocity direct force, usually cushioned by the lips or cheek, was responsible for damage caused to the supporting structures (24,26). Another study found that the presence of cartilage in the skeletal system in children and a greenstick fracture pattern may help both soft and hard tissues absorb a traumatic force (29). In this study, high supporting tissue injury rates was responsible for the high incidence of soft tissue injuries in primary dentition.

Although soft tissue injuries are self-healing, inadequate primary treatment may result in unsightly scarring. It is important to educate primary health care providers on the proper emergency management of soft tissue injuries to reduce the long-term consequences and to educate parents about the necessity of seeking immediate treatment. Future studies of the treatment of such injuries and the patients' prognoses might be useful to provide additional information on the consequences and management of soft tissue trauma.

Conclusion

Soft tissue injuries are occasionally seen in dentoalveolar traumas. The severity, type, and localization of the trauma seem to be more important factors than gender and age in the occurrence of soft tissue injuries. Soft tissue injuries were frequently seen in the maxillary region, and they were accompanied by supporting tissue injuries. The most common soft tissue injuries were lacerations, and abrasions were common in perioral tissues.
